The Department of Conservation says it is still searching for the owner of a dog that killed a baby fur seal on an Auckland Beach last week.
Department spokesman Nick Hirst confirmed it was continuing to investigate the incident but would not give any details on progress.
"What we are talking about is a potential prosecution, we are trying to find [the owner] and charge them. We're not in a situation where we can say more," he said today.
The attack was believed to have taken place near Otakamiro Point at Muriwai where dogs are prohibited.
Retired landscape photographer Bin Bai and his wife Mingua Yu saw the dog shaking and biting the young seal and carrying it by the throat. Mr Bai took photos of the attack.
